slightliy disappointedAfter years of a rusting porcelain sink I was really looking forward to my new sink. The quality is good, but it seems that it stains very easily and so where I used to just rinse sink out to get items in sink down the drain I need to cleanse with special cleanser to keep looking new. I still would have bought as it was the only sink in the size I had to have for the space requirements, and didn't want stainless but it is just going to take time to get used to it.

Swanstone

Swanstone Corporate Statement
For more than four decades, we have been a quiet leader in the kitchen and bath industry. Our high-quality products have always balanced durability, value and style. Innovation is one of our core values, and we have set a standard with our ability to invent. Now it's time to reinvent.
The Swan Story
For more than 40 years, we've been creating innovative and affordable solid surface products and materials for customers all over the world. It started in 1964, when we introduced the Swan Shell Shower, a doorless, shell-shaped shower that captured the spirit of its time.
The Shell Shower was the first in a long line of original kitchen and bath products from Swan, including the Circle Shower as well as the industry's first non-ceramic tile bathtub wall system.
In 1987, we introduced Swanstone to the world, first with a line of vanity tops and bowls. Swanstone quickly became known for its superior impact strength, heat resistance, and ability to resist scratches and stains. Consumers now had an elegant and durable solid surface material that was also affordable.
Since then, our Swanstone line has expanded to include a wide variety of kitchen sinks, countertops, tub and shower walls, and more. In 1994 we introduced the Swanstone 1/4" sheet program, offering even more flexibility to Swanstone customers. In 1997 we introduced a complete line of Swanstone products for the restaurant industry, including tabletops, countertops, vanity tops, mop service sinks and windowsills.
At Swan, we're committed to a policy of continuous improvement, to providing our customers with the highest quality products and most responsive customer service in the kitchen & bath industry. And we stand behind this commitment with some of the best warranties in the business.
Made in America
The Swan Corporation is headquartered in St. Louis, Missouri, with manufacturing facilities in Centralia, Illinois.
We proudly manufacture all products made from these material systems in the USA.
